Limited privilege escalation where a site administrator could deactivate network-wide plugins when running a WordPress network under particular circumstances, disclosed by Jon Cave of our WordPress core security team, and Adam Backstrom.

Cross-site scripting vulnerability when making URLs clickable, by Jon Cave.

Cross-site scripting vulnerabilities in redirects after posting comments in older browsers, and when filtering URLs. Thanks to Mauro Gentile for responsibly disclosing these issues to the security team.

These issues were fixed by the WordPress core security team. Five other bugs were also fixed in version 3.3.2. Consult the change log for more details.

WordPress 3.4 Beta 3 also available

Our development of WordPress 3.4 development continues. Today we are proud to release Beta 3 for testing. Nearly 90 changes have been made since Beta 2, released 9 days ago. (We are aiming for a beta every week.)

This is still beta software, so we don’t recommend that you use it on production sites. But if you’re a plugin developer, a theme developer, or a site administrator, you should be running this on your test environments and reporting any bugs you find. (See the known issues here.) If you’re a WordPress user who wants to open your presents early, take advantage of WordPress’s famous 5-minute install and spin up a secondary test site. Let us know what you think!
